Design outcomes

Primary

MeasureTime frame
Primary outcomes assess feasibility via recruitment success, adherence to ketogenic intervention, completion of study assessments, and participant retention over the 12-week intervention period.

Secondary

MeasureTime frame
Participant self-reported feasibility will be assessed at the end of the 12-week intervention using quantitative items (including a global rating on a 0–10 Likert scale with thresholds and standardized questions on acceptability, appropriateness, and feasibility) as well as qualitative open-ended questions on helpful and challenging aspects, barriers, facilitators, suggestions for improvement, and recommendations, with the qualitative data serving to contextualize and enrich the quantitative outcomes. Exploratory endpoints include psychological outcomes such as changes in PTSD symptom severity, general mental health and functioning, as well as daily EMA symptom monitoring and BHB measurements, to investigate temporal associations between ketone levels and symptom fluctuations. Additionally, physiological and metabolic parameters, including inflammatory and mitochondrial markers as well as immunometabolic analyses, are collected to explore pathophysiological mechanisms.
